SSKJ Dev ceb1170969 Add adaptive results and configuration files for sglang experiment
- Created adaptive_summary.md to summarize adaptive concurrency search results, including metrics such as TP, DP, and TPS.
- Added run_manifest.json to document experiment configuration details, including hardware specifications and search parameters.
- Introduced shapes.tsv to define input and output lengths for various configurations in the adaptive experiment.

DSV4 DSpark H20 vLLM TP×DP Matrix Benchmark

NVIDIA H20 + vLLM (Docker) + DeepSeek-V4-Flash-DSpark TP×DP matrix benchmark.

Adapted from experiments/h20/dsv4_h20_vllm_tp_dp_matrix, with the model swapped to /data1/hf_models/DeepSeek-V4-Flash-DSpark and DSpark speculative decoding enabled (aligned with experiments/h200/dsv4_h200_vllm_dspark_vs_default):

  • --spec-method dspark --spec-model <MODEL_PATH> --spec-tokens 5
  • --tokenizer-mode deepseek_v4 --reasoning-parser deepseek_v4
  • --no-disable-hybrid-kv-cache-manager --disable-uvicorn-access-log

All other parameters (KV cache fp8, block size 256, max-model-len 1M, max-num-seqs 128, ISL/OSL matrix, concurrency rules) are identical to the non-DSpark H20 vLLM matrix experiment.

Requirements

The serving environment must include a vLLM build with dspark speculative decoding support (the stock vllm/vllm-openai:latest image may not). Either:

  • point DOCKER_IMAGE to an image with dspark support, or
  • set USE_DOCKER=0 and VENV_VLLM to a native env with dspark support.

Quick Start

# Dry run: print server args and scenario plan only
DRY_RUN=1 bash experiments/h20/dsv4_dspark_h20_vllm_tp_dp_matrix/run_bench.sh

# Full TP×DP matrix run
bash experiments/h20/dsv4_dspark_h20_vllm_tp_dp_matrix/run_bench.sh

# Adaptive concurrency search (+16 per step, aligned with
# dsv4_h20_vllm_tp_dp_matrix/run_adaptive_concurrency_add16.sh)
bash experiments/h20/dsv4_dspark_h20_vllm_tp_dp_matrix/run_adaptive_concurrency_add16.sh

Results land in experiments/h20/dsv4_dspark_h20_vllm_tp_dp_matrix/results/<RUN_ID>/.

Configuration

Edit config.env or override via environment variables:

MODEL_PATH=/data1/hf_models/DeepSeek-V4-Flash-DSpark \
VLLM_PORT=30032 \
SPEC_TOKENS=5 \
bash experiments/h20/dsv4_dspark_h20_vllm_tp_dp_matrix/run_bench.sh

Cold-start note: the DSpark draft model compiles ~140 TileLang kernels plus CUDA graphs on first launch, which exceeds vLLM's default 600s engine-ready timeout. config.env therefore sets VLLM_ENGINE_READY_TIMEOUT_S=3600 and HEALTH_CHECK_RETRIES=720 (60min), and start_vllm_docker.sh persists the TileLang/DeepGEMM JIT caches under runtime/cache/ so later TP×DP configs and reruns start much faster.

Files

Same layout as dsv4_h20_vllm_tp_dp_matrix; see that experiment for details.

Platform

This experiment targets platforms/nvidia_h20.env.
